Classification of conformally harmonic Z-recurrent spacetime in F(R)-gravity

Abstract

In this paper, we give some classification of conformally harmonic [Formula: see text]-recurrent spacetime in the context of [Formula: see text]-gravity theory based on its scalar curvature and obtained the expression for energy density and isotopic pressure. Their behaviors along with EoS parameter are analyzed by considering two [Formula: see text]-gravity models. Moreover, the energy conditions for the considered models are studied and found to support the accelerated expansion of the universe.
